Changelog
### 7.6.2
```
--------------------------
- Dropped support for Python 3.8 and PyPy 3.8.
- Fix: a final wildcard match/case clause assigning to a name (``case _ as
value``) was incorrectly marked as a missing branch. This is now fixed,
closing `issue 1860`_.
- Fewer things are considered branches now. Lambdas, comprehensions, and
generator expressions are no longer marked as missing branches if they don't
complete execution.
- Fix: the HTML report didn't properly show multi-line f-strings that end with
a backslash continuation. This is now fixed, closing `issue 1836`_, thanks
to `LiuYinCarl and Marco Ricci <pull 1838_>`_.
- Fix: the LCOV report now has correct line numbers (fixing `issue 1846`_`) and
better branch descriptions for BRDA records (fixing `issue 1850`_). There
are other changes to lcov also, including a new configuration option
:ref:`line_checksums <config_lcov_line_checksums>` to control whether line
checksums are included in the lcov report. The default is false. To keep
checksums set it to true. All this work is thanks to Zack Weinberg
(`pull 1849_` and `pull 1851`_).
- Fixed the docs for multi-line regex exclusions, closing `issue 1863`_.
- Fixed a potential crash in the C tracer, closing `issue 1835`_, thanks to
`Jan Kühle <pull 1843_>`_.

### 7.6.1
```
--------------------------
- Fix: coverage used to fail when measuring code using :func:`runpy.run_path
<python:runpy.run_path>` with a :class:`Path <python:pathlib.Path>` argument.
This is now fixed, thanks to `Ask Hjorth Larsen <pull 1819_>`_.
- Fix: backslashes preceding a multi-line backslashed string could confuse the
HTML report. This is now fixed, thanks to `LiuYinCarl <pull 1828_>`_.
- Now we publish wheels for Python 3.13, both regular and free-threaded.

```
### 7.6.0
```
--------------------------
- Exclusion patterns can now be multi-line, thanks to `Daniel Diniz <pull
1807_>`_. This enables many interesting exclusion use-cases, including those
requested in issues `118 <issue 118_>`_ (entire files), `996
<issue 996_>`_ (multiple lines only when appearing together), `1741
<issue 1741_>`_ (remainder of a function), and `1803 <issue 1803_>`_
(arbitrary sequence of marked lines). See the :ref:`multi_line_exclude`
section of the docs for more details and examples.
- The JSON report now includes per-function and per-class coverage information.
Thanks to `Daniel Diniz <pull 1809_>`_ for getting the work started. This
closes `issue 1793`_ and `issue 1532`_.
- Fixed an incorrect calculation of "(no class)" lines in the HTML classes
report.
- Python 3.13.0b3 is supported.

```
### 7.5.4
```
--------------------------
- If you attempt to combine statement coverage data with branch coverage data,
coverage.py used to fail with the message "Can't combine arc data with line
data" or its reverse, "Can't combine line data with arc data." These
messages used internal terminology, making it hard for people to understand
the problem. They are now changed to mention "branch coverage data" and
"statement coverage data."
- Fixed a minor branch coverage problem with wildcard match/case cases using
names or guard clauses.
- Started testing on 3.13 free-threading (nogil) builds of Python. I'm not
claiming full support yet. Closes `issue 1799`_.
.. _issue 1799: https://github.com/nedbat/coveragepy/issues/1799
.. _changes_7-5-3:
```
### 7.5.3
```
--------------------------
- Performance improvements for combining data files, especially when measuring
line coverage. A few different quadratic behaviors were eliminated. In one
extreme case of combining 700+ data files, the time dropped from more than
three hours to seven minutes. Thanks for Kraken Tech for funding the fix.
- Performance improvements for generating HTML reports, with a side benefit of
reducing memory use, closing `issue 1791`_. Thanks to Daniel Diniz for
helping to diagnose the problem.
.. _issue 1791: https://github.com/nedbat/coveragepy/issues/1791
.. _changes_7-5-2:
```
### 7.5.2
```
--------------------------
- Fix: nested matches of exclude patterns could exclude too much code, as
reported in `issue 1779`_. This is now fixed.
- Changed: previously, coverage.py would consider a module docstring to be an
executable statement if it appeared after line 1 in the file, but not
executable if it was the first line. Now module docstrings are never counted
as executable statements. This can change coverage.py's count of the number
of statements in a file, which can slightly change the coverage percentage
reported.
- In the HTML report, the filter term and "hide covered" checkbox settings are
remembered between viewings, thanks to `Daniel Diniz <pull 1776_>`_.
- Python 3.13.0b1 is supported.
- Fix: parsing error handling is improved to ensure bizarre source files are
handled gracefully, and to unblock oss-fuzz fuzzing, thanks to `Liam DeVoe
<pull 1788_>`_. Closes `issue 1787`_.
.. _pull 1776: https://github.com/nedbat/coveragepy/pull/1776

.. _pull 1788: https://github.com/nedbat/coveragepy/pull/1788
.. _changes_7-5-1:
```
### 7.5.1
```
--------------------------
- Fix: a pragma comment on the continuation lines of a multi-line statement
now excludes the statement and its body, the same as if the pragma is
on the first line. This closes `issue 754`_. The fix was contributed by
`Daniel Diniz <pull 1773_>`_.
- Fix: very complex source files like `this one <resolvent_lookup_>`_ could
cause a maximum recursion error when creating an HTML report. This is now
fixed, closing `issue 1774`_.
- HTML report improvements:
- Support files (JavaScript and CSS) referenced by the HTML report now have
hashes added to their names to ensure updated files are used instead of
stale cached copies.
- Missing branch coverage explanations that said "the condition was never
false" now read "the condition was always true" because it's easier to
understand.
- Column sort order is remembered better as you move between the index pages,
fixing `issue 1766`_. Thanks, `Daniel Diniz <pull 1768_>`_.
.. _resolvent_lookup: https://github.com/sympy/sympy/blob/130950f3e6b3f97fcc17f4599ac08f70fdd2e9d4/sympy/polys/numberfields/resolvent_lookup.py

```
### 7.5.0
```
--------------------------
- Added initial support for function and class reporting in the HTML report.
There are now three index pages which link to each other: files, functions,
and classes. Other reports don't yet have this information, but it will be
added in the future where it makes sense. Feedback gladly accepted!
Finishes `issue 780`_.
- Other HTML report improvements:
- There is now a "hide covered" checkbox to filter out 100% files, finishing
`issue 1384`_.
- The index page is always sorted by one of its columns, with clearer
indications of the sorting.
- The "previous file" shortcut key didn't work on the index page, but now it
does, fixing `issue 1765`_.
- The debug output showing which configuration files were tried now shows
absolute paths to help diagnose problems where settings aren't taking effect,
and is renamed from "attempted_config_files" to the more logical
"config_files_attempted."
- Python 3.13.0a6 is supported.
.. _issue 780: https://github.com/nedbat/coveragepy/issues/780
.. _issue 1384: https://github.com/nedbat/coveragepy/issues/1384
.. _issue 1765: https://github.com/nedbat/coveragepy/issues/1765
.. _changes_7-4-4:
```
### 7.4.4
```
--------------------------
- Fix: in some cases, even with ``[run] relative_files=True``, a data file
could be created with absolute path names. When combined with other relative
data files, it was random whether the absolute file names would be made
relative or not. If they weren't, then a file would be listed twice in
reports, as detailed in `issue 1752`_. This is now fixed: absolute file
names are always made relative when combining. Thanks to Bruno Rodrigues dos
Santos for support.
- Fix: the last case of a match/case statement had an incorrect message if the
branch was missed. It said the pattern never matched, when actually the
branch is missed if the last case always matched.
- Fix: clicking a line number in the HTML report now positions more accurately.
- Fix: the ``report:format`` setting was defined as a boolean, but should be a
string. Thanks, `Tanaydin Sirin <pull 1754_>`_. It is also now documented
on the :ref:`configuration page <config_report_format>`.
.. _issue 1752: https://github.com/nedbat/coveragepy/issues/1752
.. _pull 1754: https://github.com/nedbat/coveragepy/pull/1754
.. _changes_7-4-3:
```
### 7.4.3
```
--------------------------
- Fix: in some cases, coverage could fail with a RuntimeError: "Set changed
size during iteration." This is now fixed, closing `issue 1733`_.
.. _issue 1733: https://github.com/nedbat/coveragepy/issues/1733
.. _changes_7-4-2:
```
### 7.4.2
```
--------------------------
- Fix: setting ``COVERAGE_CORE=sysmon`` no longer errors on 3.11 and lower,
thanks `Hugo van Kemenade <pull 1747_>`_. It now issues a warning that
sys.monitoring is not available and falls back to the default core instead.
.. _pull 1747: https://github.com/nedbat/coveragepy/pull/1747
.. _changes_7-4-1:
```
### 7.4.1
```
--------------------------
- Python 3.13.0a3 is supported.
- Fix: the JSON report now includes an explicit format version number, closing
`issue 1732`_.
.. _issue 1732: https://github.com/nedbat/coveragepy/issues/1732
.. _changes_7-4-0:
```
### 7.4.0
```
--------------------------
- In Python 3.12 and above, you can try an experimental core based on the new
:mod:`sys.monitoring <python:sys.monitoring>` module by defining a
``COVERAGE_CORE=sysmon`` environment variable. This should be faster for
line coverage, but not for branch coverage, and plugins and dynamic contexts
are not yet supported with it. I am very interested to hear how it works (or
doesn't!) for you.
.. _changes_7-3-4:
```
### 7.3.4
```
--------------------------
- Fix: the change for multi-line signature exclusions in 7.3.3 broke other
forms of nested clauses being excluded properly. This is now fixed, closing
`issue 1713`_.
- Fix: in the HTML report, selecting code for copying won't select the line
numbers also. Thanks, `Robert Harris <pull 1717_>`_.
.. _issue 1713: https://github.com/nedbat/coveragepy/issues/1713
.. _pull 1717: https://github.com/nedbat/coveragepy/pull/1717
.. _changes_7-3-3:
```
### 7.3.3
```
--------------------------
- Fix: function definitions with multi-line signatures can now be excluded by
matching any of the lines, closing `issue 684`_. Thanks, `Jan Rusak,
Maciej Kowalczyk and Joanna Ejzel <pull 1705_>`_.
- Fix: XML reports could fail with a TypeError if files had numeric components
that were duplicates except for leading zeroes, like ``file1.py`` and
``file001.py``. Fixes `issue 1709`_.
- The ``coverage annotate`` command used to announce that it would be removed
in a future version. Enough people got in touch to say that they use it, so
it will stay. Don't expect it to keep up with other new features though.
- Added new :ref:`debug options <cmd_run_debug>`:
- ``pytest`` writes the pytest test name into the debug output.
- ``dataop2`` writes the full data being added to CoverageData objects.
.. _issue 684: https://github.com/nedbat/coveragepy/issues/684
.. _pull 1705: https://github.com/nedbat/coveragepy/pull/1705
.. _issue 1709: https://github.com/nedbat/coveragepy/issues/1709
.. _changes_7-3-2:
```
### 7.3.2
```
--------------------------
- The ``coverage lcov`` command ignored the ``[report] exclude_lines`` and
``[report] exclude_also`` settings (`issue 1684`_). This is now fixed,
thanks `Jacqueline Lee <pull 1685_>`_.
- Sometimes SQLite will create journal files alongside the coverage.py database
files. These are ephemeral, but could be mistakenly included when combining
data files. Now they are always ignored, fixing `issue 1605`_. Thanks to
Brad Smith for suggesting fixes and providing detailed debugging.
- On Python 3.12+, we now disable SQLite writing journal files, which should be
a little faster.
- The new 3.12 soft keyword ``type`` is properly bolded in HTML reports.
- Removed the "fullcoverage" feature used by CPython to measure the coverage of
early-imported standard library modules. CPython `stopped using it
<88054_>`_ in 2021, and it stopped working completely in Python 3.13.

.. _changes_7-3-1:
```
### 7.3.1
```
--------------------------
- The semantics of stars in file patterns has been clarified in the docs. A
leading or trailing star matches any number of path components, like a double
star would. This is different than the behavior of a star in the middle of a
pattern. This discrepancy was `identified by Sviatoslav Sydorenko
<starbad_>`_, who `provided patient detailed diagnosis <pull 1650_>`_ and
graciously agreed to a pragmatic resolution.
- The API docs were missing from the last version. They are now `restored
<apidocs_>`_.
.. _apidocs: https://coverage.readthedocs.io/en/latest/api_coverage.html
.. _starbad: https://github.com/nedbat/coveragepy/issues/1407#issuecomment-1631085209
.. _pull 1650: https://github.com/nedbat/coveragepy/pull/1650
.. _changes_7-3-0:
```
### 7.3.0
```
--------------------------
- Added a :meth:`.Coverage.collect` context manager to start and stop coverage
data collection.
- Dropped support for Python 3.7.
- Fix: in unusual circumstances, SQLite cannot be set to asynchronous mode.
Coverage.py would fail with the error ``Safety level may not be changed
inside a transaction.`` This is now avoided, closing `issue 1646`_. Thanks
to Michael Bell for the detailed bug report.
- Docs: examples of configuration files now include separate examples for the
different syntaxes: .coveragerc, pyproject.toml, setup.cfg, and tox.ini.
- Fix: added ``nosemgrep`` comments to our JavaScript code so that
semgrep-based SAST security checks won't raise false alarms about security
problems that aren't problems.
- Added a CITATION.cff file, thanks to `Ken Schackart <pull 1641_>`_.
.. _pull 1641: https://github.com/nedbat/coveragepy/pull/1641
.. _issue 1646: https://github.com/nedbat/coveragepy/issues/1646
.. _changes_7-2-7:
```
### 7.2.7
```
--------------------------
- Fix: reverted a `change from 6.4.3 <pull 1347b_>`_ that helped Cython, but
also increased the size of data files when using dynamic contexts, as
described in the now-fixed `issue 1586`_. The problem is now avoided due to a
recent change (`issue 1538 <issue 1538b_>`_). Thanks to `Anders Kaseorg
<pull 1629_>`_ and David Szotten for persisting with problem reports and
detailed diagnoses.
- Wheels are now provided for CPython 3.12.
.. _pull 1347b: https://github.com/nedbat/coveragepy/pull/1347

.. _pull 1629: https://github.com/nedbat/coveragepy/pull/1629
.. _changes_7-2-6:
```
### 7.2.6
```
--------------------------
- Fix: the ``lcov`` command could raise an IndexError exception if a file is
translated to Python but then executed under its own name. Jinja2 does this
when rendering templates. Fixes `issue 1553`_.
- Python 3.12 beta 1 now inlines comprehensions. Previously they were compiled
as invisible functions and coverage.py would warn you if they weren't
completely executed. This no longer happens under Python 3.12.
- Fix: the ``coverage debug sys`` command includes some environment variables
in its output. This could have included sensitive data. Those values are
now hidden with asterisks, closing `issue 1628`_.
.. _issue 1553: https://github.com/nedbat/coveragepy/issues/1553
.. _issue 1628: https://github.com/nedbat/coveragepy/issues/1628
.. _changes_7-2-5:
```
### 7.2.5
```
--------------------------
- Fix: ``html_report()`` could fail with an AttributeError on ``isatty`` if run
in an unusual environment where sys.stdout had been replaced. This is now
fixed.
.. _changes_7-2-4:
```
### 7.2.4
```
--------------------------
PyCon 2023 sprint fixes!
- Fix: with ``relative_files = true``, specifying a specific file to include or
omit wouldn't work correctly (`issue 1604`_). This is now fixed, with
testing help by `Marc Gibbons <pull 1608_>`_.
- Fix: the XML report would have an incorrect ``<source>`` element when using
relative files and the source option ended with a slash (`issue 1541`_).
This is now fixed, thanks to `Kevin Brown-Silva <pull 1608_>`_.
- When the HTML report location is printed to the terminal, it's now a
terminal-compatible URL, so that you can click the location to open the HTML
file in your browser. Finishes `issue 1523`_ thanks to `Ricardo Newbery
<pull 1613_>`_.
- Docs: a new :ref:`Migrating page <migrating>` with details about how to
migrate between major versions of coverage.py. It currently covers the
wildcard changes in 7.x. Thanks, `Brian Grohe <pull 1610_>`_.

```
### 7.2.3
```
--------------------------
- Fix: the :ref:`config_run_sigterm` setting was meant to capture data if a
process was terminated with a SIGTERM signal, but it didn't always. This was
fixed thanks to `Lewis Gaul <pull 1600_>`_, closing `issue 1599`_.
- Performance: HTML reports with context information are now much more compact.
File sizes are typically as small as one-third the previous size, but can be
dramatically smaller. This closes `issue 1584`_ thanks to `Oleh Krehel
<pull 1587_>`_.
- Development dependencies no longer use hashed pins, closing `issue 1592`_.

```
### 7.2.2
```
--------------------------
- Fix: if a virtualenv was created inside a source directory, and a sourced
package was installed inside the virtualenv, then all of the third-party
packages inside the virtualenv would be measured. This was incorrect, but
has now been fixed: only the specified packages will be measured, thanks to
`Manuel Jacob <pull 1560_>`_.
- Fix: the ``coverage lcov`` command could create a .lcov file with incorrect
LF (lines found) and LH (lines hit) totals. This is now fixed, thanks to
`Ian Moore <pull 1583_>`_.
- Fix: the ``coverage xml`` command on Windows could create a .xml file with
duplicate ``<package>`` elements. This is now fixed, thanks to `Benjamin
Parzella <pull 1574_>`_, closing `issue 1573`_.

```
### 7.2.1
```
--------------------------
- Fix: the PyPI page had broken links to documentation pages, but no longer
does, closing `issue 1566`_.
- Fix: public members of the coverage module are now properly indicated so that
mypy will find them, fixing `issue 1564`_.

```
### 7.2.0
```
--------------------------
- Added a new setting ``[report] exclude_also`` to let you add more exclusions
without overwriting the defaults. Thanks, `Alpha Chen <pull 1557_>`_,
closing `issue 1391`_.
- Added a :meth:`.CoverageData.purge_files` method to remove recorded data for
a particular file. Contributed by `Stephan Deibel <pull 1547_>`_.
- Fix: when reporting commands fail, they will no longer congratulate
themselves with messages like "Wrote XML report to file.xml" before spewing a
traceback about their failure.
- Fix: arguments in the public API that name file paths now accept pathlib.Path
objects. This includes the ``data_file`` and ``config_file`` arguments to
the Coverage constructor and the ``basename`` argument to CoverageData.
Closes `issue 1552`_.
- Fix: In some embedded environments, an IndexError could occur on stop() when
the originating thread exits before completion. This is now fixed, thanks to
`Russell Keith-Magee <pull 1543_>`_, closing `issue 1542`_.
- Added a ``py.typed`` file to announce our type-hintedness. Thanks,
`KotlinIsland <pull 1550_>`_.

### 7.1.0
```
--------------------------
- Added: the debug output file can now be specified with ``[run] debug_file``
in the configuration file. Closes `issue 1319`_.
- Performance: fixed a slowdown with dynamic contexts that's been around since
6.4.3. The fix closes `issue 1538`_. Thankfully this doesn't break the
`Cython change`_ that fixed `issue 972`_. Thanks to Mathieu Kniewallner for
the deep investigative work and comprehensive issue report.
- Typing: all product and test code has type annotations.

### 7.0.5
```
--------------------------
- Fix: On Python 3.7, a file with type annotations but no ``from __future__
import annotations`` would be missing statements in the coverage report. This
is now fixed, closing `issue 1524`_.

```
### 7.0.4
```
--------------------------
- Performance: an internal cache of file names was accidentally disabled,
resulting in sometimes drastic reductions in performance. This is now fixed,
closing `issue 1527`_. Thanks to Ivan Ciuvalschii for the reproducible test
case.

```
### 7.0.3
```
--------------------------
- Fix: when using pytest-cov or pytest-xdist, or perhaps both, the combining
step could fail with ``assert row is not None`` using 7.0.2. This was due to
a race condition that has always been possible and is still possible. In
7.0.1 and before, the error was silently swallowed by the combining code.
Now it will produce a message "Couldn't combine data file" and ignore the
data file as it used to do before 7.0.2. Closes `issue 1522`_.
.. _issue 1522: https://github.com/nedbat/coveragepy/issues/1522
.. _changes_7-0-2:
```
### 7.0.2
```
--------------------------
- Fix: when using the ``[run] relative_files = True`` setting, a relative
``[paths]`` pattern was still being made absolute. This is now fixed,
closing `issue 1519`_.
- Fix: if Python doesn't provide tomllib, then TOML configuration files can
only be read if coverage.py is installed with the ``[toml]`` extra.
Coverage.py will raise an error if TOML support is not installed when it sees
your settings are in a .toml file. But it didn't understand that
``[tools.coverage]`` was a valid section header, so the error wasn't reported
if you used that header, and settings were silently ignored. This is now
fixed, closing `issue 1516`_.
- Fix: adjusted how decorators are traced on PyPy 7.3.10, fixing `issue 1515`_.
- Fix: the ``coverage lcov`` report did not properly implement the
``--fail-under=MIN`` option. This has been fixed.
- Refactor: added many type annotations, including a number of refactorings.
This should not affect outward behavior, but they were a bit invasive in some
places, so keep your eyes peeled for oddities.
- Refactor: removed the vestigial and long untested support for Jython and
IronPython.

### 7.0.1
```
--------------------------
- When checking if a file mapping resolved to a file that exists, we weren't
considering files in .whl files. This is now fixed, closing `issue 1511`_.
- File pattern rules were too strict, forbidding plus signs and curly braces in
directory and file names. This is now fixed, closing `issue 1513`_.
- Unusual Unicode or control characters in source files could prevent
reporting. This is now fixed, closing `issue 1512`_.
- The PyPy wheel now installs on PyPy 3.7, 3.8, and 3.9, closing `issue 1510`_.

### 7.0.0b1
```
----------------------------
A number of changes have been made to file path handling, including pattern
matching and path remapping with the ``[paths]`` setting (see
:ref:`config_paths`). These changes might affect you, and require you to
update your settings.
(This release includes the changes from `6.6.0b1`__, since 6.6.0 was never
released.)
__ https://coverage.readthedocs.io/en/latest/changes.html#changes-6-6-0b1
- Changes to file pattern matching, which might require updating your
configuration:
- Previously, ``*`` would incorrectly match directory separators, making
precise matching difficult. This is now fixed, closing `issue 1407`_.
- Now ``**`` matches any number of nested directories, including none.
- Improvements to combining data files when using the
:ref:`config_run_relative_files` setting, which might require updating your
configuration:
- During ``coverage combine``, relative file paths are implicitly combined
without needing a ``[paths]`` configuration setting. This also fixed
`issue 991`_.
- A ``[paths]`` setting like ``*/foo`` will now match ``foo/bar.py`` so that
relative file paths can be combined more easily.
- The :ref:`config_run_relative_files` setting is properly interpreted in
more places, fixing `issue 1280`_.
- When remapping file paths with ``[paths]``, a path will be remapped only if
the resulting path exists. The documentation has long said the prefix had to
exist, but it was never enforced. This fixes `issue 608`_, improves `issue
649`_, and closes `issue 757`_.
- Reporting operations now implicitly use the ``[paths]`` setting to remap file
paths within a single data file. Combining multiple files still requires the
``coverage combine`` step, but this simplifies some single-file situations.
Closes `issue 1212`_ and `issue 713`_.
- The ``coverage report`` command now has a ``--format=`` option. The original
style is now ``--format=text``, and is the default.
- Using ``--format=markdown`` will write the table in Markdown format, thanks
to `Steve Oswald <pull 1479_>`_, closing `issue 1418`_.
- Using ``--format=total`` will write a single total number to the
output. This can be useful for making badges or writing status updates.
- Combining data files with ``coverage combine`` now hashes the data files to
skip files that add no new information. This can reduce the time needed.
Many details affect the speed-up, but for coverage.py's own test suite,
combining is about 40% faster. Closes `issue 1483`_.
- When searching for completely un-executed files, coverage.py uses the
presence of ``__init__.py`` files to determine which directories have source
that could have been imported. However, `implicit namespace packages`_ don't
require ``__init__.py``. A new setting ``[report]
include_namespace_packages`` tells coverage.py to consider these directories
during reporting. Thanks to `Felix Horvat <pull 1387_>`_ for the
contribution. Closes `issue 1383`_ and `issue 1024`_.
- Fixed environment variable expansion in pyproject.toml files. It was overly
broad, causing errors outside of coverage.py settings, as described in `issue
1481`_ and `issue 1345`_. This is now fixed, but in rare cases will require
changing your pyproject.toml to quote non-string values that use environment
substitution.
- An empty file has a coverage total of 100%, but used to fail with
``--fail-under``. This has been fixed, closing `issue 1470`_.
- The text report table no longer writes out two separator lines if there are
no files listed in the table. One is plenty.
- Fixed a mis-measurement of a strange use of wildcard alternatives in
match/case statements, closing `issue 1421`_.
- Fixed internal logic that prevented coverage.py from running on
implementations other than CPython or PyPy (`issue 1474`_).
- The deprecated ``[run] note`` setting has been completely removed.

Changelog
### 7.6.2 ``` -------------------------- - Dropped support for Python 3.8 and PyPy 3.8. - Fix: a final wildcard match/case clause assigning to a name (``case _ as value``) was incorrectly marked as a missing branch. This is now fixed, closing `issue 1860`_. - Fewer things are considered branches now. Lambdas, comprehensions, and generator expressions are no longer marked as missing branches if they don't complete execution. - Fix: the HTML report didn't properly show multi-line f-strings that end with a backslash continuation. This is now fixed, closing `issue 1836`_, thanks to `LiuYinCarl and Marco Ricci <pull 1838_>`_. - Fix: the LCOV report now has correct line numbers (fixing `issue 1846`_`) and better branch descriptions for BRDA records (fixing `issue 1850`_). There are other changes to lcov also, including a new configuration option :ref:`line_checksums <config_lcov_line_checksums>` to control whether line checksums are included in the lcov report. The default is false. To keep checksums set it to true. All this work is thanks to Zack Weinberg (`pull 1849_` and `pull 1851`_). - Fixed the docs for multi-line regex exclusions, closing `issue 1863`_. - Fixed a potential crash in the C tracer, closing `issue 1835`_, thanks to `Jan Kühle <pull 1843_>`_. .. _issue 1835: https://github.com/nedbat/coveragepy/issues/1835 .. _issue 1836: https://github.com/nedbat/coveragepy/issues/1836 .. _pull 1838: https://github.com/nedbat/coveragepy/pull/1838 .. _pull 1843: https://github.com/nedbat/coveragepy/pull/1843 .. _issue 1846: https://github.com/nedbat/coveragepy/issues/1846 .. _pull 1849: https://github.com/nedbat/coveragepy/pull/1849 .. _issue 1850: https://github.com/nedbat/coveragepy/issues/1850 .. _pull 1851: https://github.com/nedbat/coveragepy/pull/1851 .. _issue 1860: https://github.com/nedbat/coveragepy/issues/1860 .. _issue 1863: https://github.com/nedbat/coveragepy/issues/1863 .. _changes_7-6-1: ``` ### 7.6.1 ``` -------------------------- - Fix: coverage used to fail when measuring code using :func:`runpy.run_path <python:runpy.run_path>` with a :class:`Path <python:pathlib.Path>` argument. This is now fixed, thanks to `Ask Hjorth Larsen <pull 1819_>`_. - Fix: backslashes preceding a multi-line backslashed string could confuse the HTML report. This is now fixed, thanks to `LiuYinCarl <pull 1828_>`_. - Now we publish wheels for Python 3.13, both regular and free-threaded. .. _pull 1819: https://github.com/nedbat/coveragepy/pull/1819 .. _pull 1828: https://github.com/nedbat/coveragepy/pull/1828 .. _changes_7-6-0: ``` ### 7.6.0 ``` -------------------------- - Exclusion patterns can now be multi-line, thanks to `Daniel Diniz <pull 1807_>`_. This enables many interesting exclusion use-cases, including those requested in issues `118 <issue 118_>`_ (entire files), `996 <issue 996_>`_ (multiple lines only when appearing together), `1741 <issue 1741_>`_ (remainder of a function), and `1803 <issue 1803_>`_ (arbitrary sequence of marked lines). See the :ref:`multi_line_exclude` section of the docs for more details and examples. - The JSON report now includes per-function and per-class coverage information. Thanks to `Daniel Diniz <pull 1809_>`_ for getting the work started. This closes `issue 1793`_ and `issue 1532`_. - Fixed an incorrect calculation of "(no class)" lines in the HTML classes report. - Python 3.13.0b3 is supported. .. _issue 118: https://github.com/nedbat/coveragepy/issues/118 .. _issue 996: https://github.com/nedbat/coveragepy/issues/996 .. _issue 1532: https://github.com/nedbat/coveragepy/issues/1532 .. _issue 1741: https://github.com/nedbat/coveragepy/issues/1741 .. _issue 1793: https://github.com/nedbat/coveragepy/issues/1793 .. _issue 1803: https://github.com/nedbat/coveragepy/issues/1803 .. _pull 1807: https://github.com/nedbat/coveragepy/pull/1807 .. _pull 1809: https://github.com/nedbat/coveragepy/pull/1809 .. _changes_7-5-4: ``` ### 7.5.4 ``` -------------------------- - If you attempt to combine statement coverage data with branch coverage data, coverage.py used to fail with the message "Can't combine arc data with line data" or its reverse, "Can't combine line data with arc data." These messages used internal terminology, making it hard for people to understand the problem. They are now changed to mention "branch coverage data" and "statement coverage data." - Fixed a minor branch coverage problem with wildcard match/case cases using names or guard clauses. - Started testing on 3.13 free-threading (nogil) builds of Python. I'm not claiming full support yet. Closes `issue 1799`_. .. _issue 1799: https://github.com/nedbat/coveragepy/issues/1799 .. _changes_7-5-3: ``` ### 7.5.3 ``` -------------------------- - Performance improvements for combining data files, especially when measuring line coverage. A few different quadratic behaviors were eliminated. In one extreme case of combining 700+ data files, the time dropped from more than three hours to seven minutes. Thanks for Kraken Tech for funding the fix. - Performance improvements for generating HTML reports, with a side benefit of reducing memory use, closing `issue 1791`_. Thanks to Daniel Diniz for helping to diagnose the problem. .. _issue 1791: https://github.com/nedbat/coveragepy/issues/1791 .. _changes_7-5-2: ``` ### 7.5.2 ``` -------------------------- - Fix: nested matches of exclude patterns could exclude too much code, as reported in `issue 1779`_. This is now fixed. - Changed: previously, coverage.py would consider a module docstring to be an executable statement if it appeared after line 1 in the file, but not executable if it was the first line. Now module docstrings are never counted as executable statements. This can change coverage.py's count of the number of statements in a file, which can slightly change the coverage percentage reported. - In the HTML report, the filter term and "hide covered" checkbox settings are remembered between viewings, thanks to `Daniel Diniz <pull 1776_>`_. - Python 3.13.0b1 is supported. - Fix: parsing error handling is improved to ensure bizarre source files are handled gracefully, and to unblock oss-fuzz fuzzing, thanks to `Liam DeVoe <pull 1788_>`_. Closes `issue 1787`_. .. _pull 1776: https://github.com/nedbat/coveragepy/pull/1776 .. _issue 1779: https://github.com/nedbat/coveragepy/issues/1779 .. _issue 1787: https://github.com/nedbat/coveragepy/issues/1787 .. _pull 1788: https://github.com/nedbat/coveragepy/pull/1788 .. _changes_7-5-1: ``` ### 7.5.1 ``` -------------------------- - Fix: a pragma comment on the continuation lines of a multi-line statement now excludes the statement and its body, the same as if the pragma is on the first line. This closes `issue 754`_. The fix was contributed by `Daniel Diniz <pull 1773_>`_. - Fix: very complex source files like `this one <resolvent_lookup_>`_ could cause a maximum recursion error when creating an HTML report. This is now fixed, closing `issue 1774`_. - HTML report improvements: - Support files (JavaScript and CSS) referenced by the HTML report now have hashes added to their names to ensure updated files are used instead of stale cached copies. - Missing branch coverage explanations that said "the condition was never false" now read "the condition was always true" because it's easier to understand. - Column sort order is remembered better as you move between the index pages, fixing `issue 1766`_. Thanks, `Daniel Diniz <pull 1768_>`_. .. _resolvent_lookup: https://github.com/sympy/sympy/blob/130950f3e6b3f97fcc17f4599ac08f70fdd2e9d4/sympy/polys/numberfields/resolvent_lookup.py .. _issue 754: https://github.com/nedbat/coveragepy/issues/754 .. _issue 1766: https://github.com/nedbat/coveragepy/issues/1766 .. _pull 1768: https://github.com/nedbat/coveragepy/pull/1768 .. _pull 1773: https://github.com/nedbat/coveragepy/pull/1773 .. _issue 1774: https://github.com/nedbat/coveragepy/issues/1774 .. _changes_7-5-0: ``` ### 7.5.0 ``` -------------------------- - Added initial support for function and class reporting in the HTML report. There are now three index pages which link to each other: files, functions, and classes. Other reports don't yet have this information, but it will be added in the future where it makes sense. Feedback gladly accepted! Finishes `issue 780`_. - Other HTML report improvements: - There is now a "hide covered" checkbox to filter out 100% files, finishing `issue 1384`_. - The index page is always sorted by one of its columns, with clearer indications of the sorting. - The "previous file" shortcut key didn't work on the index page, but now it does, fixing `issue 1765`_. - The debug output showing which configuration files were tried now shows absolute paths to help diagnose problems where settings aren't taking effect, and is renamed from "attempted_config_files" to the more logical "config_files_attempted." - Python 3.13.0a6 is supported. .. _issue 780: https://github.com/nedbat/coveragepy/issues/780 .. _issue 1384: https://github.com/nedbat/coveragepy/issues/1384 .. _issue 1765: https://github.com/nedbat/coveragepy/issues/1765 .. _changes_7-4-4: ``` ### 7.4.4 ``` -------------------------- - Fix: in some cases, even with ``[run] relative_files=True``, a data file could be created with absolute path names. When combined with other relative data files, it was random whether the absolute file names would be made relative or not. If they weren't, then a file would be listed twice in reports, as detailed in `issue 1752`_. This is now fixed: absolute file names are always made relative when combining. Thanks to Bruno Rodrigues dos Santos for support. - Fix: the last case of a match/case statement had an incorrect message if the branch was missed. It said the pattern never matched, when actually the branch is missed if the last case always matched. - Fix: clicking a line number in the HTML report now positions more accurately. - Fix: the ``report:format`` setting was defined as a boolean, but should be a string. Thanks, `Tanaydin Sirin <pull 1754_>`_. It is also now documented on the :ref:`configuration page <config_report_format>`. .. _issue 1752: https://github.com/nedbat/coveragepy/issues/1752 .. _pull 1754: https://github.com/nedbat/coveragepy/pull/1754 .. _changes_7-4-3: ``` ### 7.4.3 ``` -------------------------- - Fix: in some cases, coverage could fail with a RuntimeError: "Set changed size during iteration." This is now fixed, closing `issue 1733`_. .. _issue 1733: https://github.com/nedbat/coveragepy/issues/1733 .. _changes_7-4-2: ``` ### 7.4.2 ``` -------------------------- - Fix: setting ``COVERAGE_CORE=sysmon`` no longer errors on 3.11 and lower, thanks `Hugo van Kemenade <pull 1747_>`_. It now issues a warning that sys.monitoring is not available and falls back to the default core instead. .. _pull 1747: https://github.com/nedbat/coveragepy/pull/1747 .. _changes_7-4-1: ``` ### 7.4.1 ``` -------------------------- - Python 3.13.0a3 is supported. - Fix: the JSON report now includes an explicit format version number, closing `issue 1732`_. .. _issue 1732: https://github.com/nedbat/coveragepy/issues/1732 .. _changes_7-4-0: ``` ### 7.4.0 ``` -------------------------- - In Python 3.12 and above, you can try an experimental core based on the new :mod:`sys.monitoring <python:sys.monitoring>` module by defining a ``COVERAGE_CORE=sysmon`` environment variable. This should be faster for line coverage, but not for branch coverage, and plugins and dynamic contexts are not yet supported with it. I am very interested to hear how it works (or doesn't!) for you. .. _changes_7-3-4: ``` ### 7.3.4 ``` -------------------------- - Fix: the change for multi-line signature exclusions in 7.3.3 broke other forms of nested clauses being excluded properly. This is now fixed, closing `issue 1713`_. - Fix: in the HTML report, selecting code for copying won't select the line numbers also. Thanks, `Robert Harris <pull 1717_>`_. .. _issue 1713: https://github.com/nedbat/coveragepy/issues/1713 .. _pull 1717: https://github.com/nedbat/coveragepy/pull/1717 .. _changes_7-3-3: ``` ### 7.3.3 ``` -------------------------- - Fix: function definitions with multi-line signatures can now be excluded by matching any of the lines, closing `issue 684`_. Thanks, `Jan Rusak, Maciej Kowalczyk and Joanna Ejzel <pull 1705_>`_. - Fix: XML reports could fail with a TypeError if files had numeric components that were duplicates except for leading zeroes, like ``file1.py`` and ``file001.py``. Fixes `issue 1709`_. - The ``coverage annotate`` command used to announce that it would be removed in a future version. Enough people got in touch to say that they use it, so it will stay. Don't expect it to keep up with other new features though. - Added new :ref:`debug options <cmd_run_debug>`: - ``pytest`` writes the pytest test name into the debug output. - ``dataop2`` writes the full data being added to CoverageData objects. .. _issue 684: https://github.com/nedbat/coveragepy/issues/684 .. _pull 1705: https://github.com/nedbat/coveragepy/pull/1705 .. _issue 1709: https://github.com/nedbat/coveragepy/issues/1709 .. _changes_7-3-2: ``` ### 7.3.2 ``` -------------------------- - The ``coverage lcov`` command ignored the ``[report] exclude_lines`` and ``[report] exclude_also`` settings (`issue 1684`_). This is now fixed, thanks `Jacqueline Lee <pull 1685_>`_. - Sometimes SQLite will create journal files alongside the coverage.py database files. These are ephemeral, but could be mistakenly included when combining data files. Now they are always ignored, fixing `issue 1605`_. Thanks to Brad Smith for suggesting fixes and providing detailed debugging. - On Python 3.12+, we now disable SQLite writing journal files, which should be a little faster. - The new 3.12 soft keyword ``type`` is properly bolded in HTML reports. - Removed the "fullcoverage" feature used by CPython to measure the coverage of early-imported standard library modules. CPython `stopped using it <88054_>`_ in 2021, and it stopped working completely in Python 3.13. .. _issue 1605: https://github.com/nedbat/coveragepy/issues/1605 .. _issue 1684: https://github.com/nedbat/coveragepy/issues/1684 .. _pull 1685: https://github.com/nedbat/coveragepy/pull/1685 .. _88054: https://github.com/python/cpython/issues/88054 .. _changes_7-3-1: ``` ### 7.3.1 ``` -------------------------- - The semantics of stars in file patterns has been clarified in the docs. A leading or trailing star matches any number of path components, like a double star would. This is different than the behavior of a star in the middle of a pattern. This discrepancy was `identified by Sviatoslav Sydorenko <starbad_>`_, who `provided patient detailed diagnosis <pull 1650_>`_ and graciously agreed to a pragmatic resolution. - The API docs were missing from the last version. They are now `restored <apidocs_>`_. .. _apidocs: https://coverage.readthedocs.io/en/latest/api_coverage.html .. _starbad: https://github.com/nedbat/coveragepy/issues/1407#issuecomment-1631085209 .. _pull 1650: https://github.com/nedbat/coveragepy/pull/1650 .. _changes_7-3-0: ``` ### 7.3.0 ``` -------------------------- - Added a :meth:`.Coverage.collect` context manager to start and stop coverage data collection. - Dropped support for Python 3.7. - Fix: in unusual circumstances, SQLite cannot be set to asynchronous mode. Coverage.py would fail with the error ``Safety level may not be changed inside a transaction.`` This is now avoided, closing `issue 1646`_. Thanks to Michael Bell for the detailed bug report. - Docs: examples of configuration files now include separate examples for the different syntaxes: .coveragerc, pyproject.toml, setup.cfg, and tox.ini. - Fix: added ``nosemgrep`` comments to our JavaScript code so that semgrep-based SAST security checks won't raise false alarms about security problems that aren't problems. - Added a CITATION.cff file, thanks to `Ken Schackart <pull 1641_>`_. .. _pull 1641: https://github.com/nedbat/coveragepy/pull/1641 .. _issue 1646: https://github.com/nedbat/coveragepy/issues/1646 .. _changes_7-2-7: ``` ### 7.2.7 ``` -------------------------- - Fix: reverted a `change from 6.4.3 <pull 1347b_>`_ that helped Cython, but also increased the size of data files when using dynamic contexts, as described in the now-fixed `issue 1586`_. The problem is now avoided due to a recent change (`issue 1538 <issue 1538b_>`_). Thanks to `Anders Kaseorg <pull 1629_>`_ and David Szotten for persisting with problem reports and detailed diagnoses. - Wheels are now provided for CPython 3.12. .. _pull 1347b: https://github.com/nedbat/coveragepy/pull/1347 .. _issue 1538b: https://github.com/nedbat/coveragepy/issues/1538 .. _issue 1586: https://github.com/nedbat/coveragepy/issues/1586 .. _pull 1629: https://github.com/nedbat/coveragepy/pull/1629 .. _changes_7-2-6: ``` ### 7.2.6 ``` -------------------------- - Fix: the ``lcov`` command could raise an IndexError exception if a file is translated to Python but then executed under its own name. Jinja2 does this when rendering templates. Fixes `issue 1553`_. - Python 3.12 beta 1 now inlines comprehensions. Previously they were compiled as invisible functions and coverage.py would warn you if they weren't completely executed. This no longer happens under Python 3.12. - Fix: the ``coverage debug sys`` command includes some environment variables in its output. This could have included sensitive data. Those values are now hidden with asterisks, closing `issue 1628`_. .. _issue 1553: https://github.com/nedbat/coveragepy/issues/1553 .. _issue 1628: https://github.com/nedbat/coveragepy/issues/1628 .. _changes_7-2-5: ``` ### 7.2.5 ``` -------------------------- - Fix: ``html_report()`` could fail with an AttributeError on ``isatty`` if run in an unusual environment where sys.stdout had been replaced. This is now fixed. .. _changes_7-2-4: ``` ### 7.2.4 ``` -------------------------- PyCon 2023 sprint fixes! - Fix: with ``relative_files = true``, specifying a specific file to include or omit wouldn't work correctly (`issue 1604`_). This is now fixed, with testing help by `Marc Gibbons <pull 1608_>`_. - Fix: the XML report would have an incorrect ``<source>`` element when using relative files and the source option ended with a slash (`issue 1541`_). This is now fixed, thanks to `Kevin Brown-Silva <pull 1608_>`_. - When the HTML report location is printed to the terminal, it's now a terminal-compatible URL, so that you can click the location to open the HTML file in your browser. Finishes `issue 1523`_ thanks to `Ricardo Newbery <pull 1613_>`_. - Docs: a new :ref:`Migrating page <migrating>` with details about how to migrate between major versions of coverage.py. It currently covers the wildcard changes in 7.x.

This was fixed thanks to `Lewis Gaul <pull 1600_>`_, closing `issue 1599`_. - Performance: HTML reports with context information are now much more compact. File sizes are typically as small as one-third the previous size, but can be dramatically smaller. This closes `issue 1584`_ thanks to `Oleh Krehel <pull 1587_>`_. - Development dependencies no longer use hashed pins, closing `issue 1592`_. .. _issue 1584: https://github.com/nedbat/coveragepy/issues/1584 .. _pull 1587: https://github.com/nedbat/coveragepy/pull/1587 .. _issue 1592: https://github.com/nedbat/coveragepy/issues/1592 .. _issue 1599: https://github.com/nedbat/coveragepy/issues/1599 .. _pull 1600: https://github.com/nedbat/coveragepy/pull/1600 .. _changes_7-2-2: ``` ### 7.2.2 ``` -------------------------- - Fix: if a virtualenv was created inside a source directory, and a sourced package was installed inside the virtualenv, then all of the third-party packages inside the virtualenv would be measured. This was incorrect, but has now been fixed: only the specified packages will be measured, thanks to `Manuel Jacob <pull 1560_>`_. - Fix: the ``coverage lcov`` command could create a .lcov file with incorrect LF (lines found) and LH (lines hit) totals. This is now fixed, thanks to `Ian Moore <pull 1583_>`_. - Fix: the ``coverage xml`` command on Windows could create a .xml file with duplicate ``<package>`` elements. This is now fixed, thanks to `Benjamin Parzella <pull 1574_>`_, closing `issue 1573`_. .. _pull 1560: https://github.com/nedbat/coveragepy/pull/1560 .. _issue 1573: https://github.com/nedbat/coveragepy/issues/1573 .. _pull 1574: https://github.com/nedbat/coveragepy/pull/1574 .. _pull 1583: https://github.com/nedbat/coveragepy/pull/1583 .. _changes_7-2-1: ``` ### 7.2.1 ``` -------------------------- - Fix: the PyPI page had broken links to documentation pages, but no longer does, closing `issue 1566`_. - Fix: public members of the coverage module are now properly indicated so that mypy will find them, fixing `issue 1564`_. .. _issue 1564: https://github.com/nedbat/coveragepy/issues/1564 .. _issue 1566: https://github.com/nedbat/coveragepy/issues/1566 .. _changes_7-2-0: ``` ### 7.2.0 ``` -------------------------- - Added a new setting ``[report] exclude_also`` to let you add more exclusions without overwriting the defaults. Thanks, `Alpha Chen <pull 1557_>`_, closing `issue 1391`_. - Added a :meth:`.CoverageData.purge_files` method to remove recorded data for a particular file. Contributed by `Stephan Deibel <pull 1547_>`_. - Fix: when reporting commands fail, they will no longer congratulate themselves with messages like "Wrote XML report to file.xml" before spewing a traceback about their failure. - Fix: arguments in the public API that name file paths now accept pathlib.Path objects. This includes the ``data_file`` and ``config_file`` arguments to the Coverage constructor and the ``basename`` argument to CoverageData. Closes `issue 1552`_. - Fix: In some embedded environments, an IndexError could occur on stop() when the originating thread exits before completion. This is now fixed, thanks to `Russell Keith-Magee <pull 1543_>`_, closing `issue 1542`_. - Added a ``py.typed`` file to announce our type-hintedness. Thanks, `KotlinIsland <pull 1550_>`_. .. _issue 1391: https://github.com/nedbat/coveragepy/issues/1391 .. _issue 1542: https://github.com/nedbat/coveragepy/issues/1542 .. _pull 1543: https://github.com/nedbat/coveragepy/pull/1543 .. _pull 1547: https://github.com/nedbat/coveragepy/pull/1547 .. _pull 1550: https://github.com/nedbat/coveragepy/pull/1550 .. _issue 1552: https://github.com/nedbat/coveragepy/issues/1552 .. _pull 1557: https://github.com/nedbat/coveragepy/pull/1557 .. _changes_7-1-0: ``` ### 7.1.0 ``` -------------------------- - Added: the debug output file can now be specified with ``[run] debug_file`` in the configuration file. Closes `issue 1319`_. - Performance: fixed a slowdown with dynamic contexts that's been around since 6.4.3. The fix closes `issue 1538`_. Thankfully this doesn't break the `Cython change`_ that fixed `issue 972`_. Thanks to Mathieu Kniewallner for the deep investigative work and comprehensive issue report. - Typing: all product and test code has type annotations. .. _Cython change: https://github.com/nedbat/coveragepy/pull/1347 .. _issue 972: https://github.com/nedbat/coveragepy/issues/972 .. _issue 1319: https://github.com/nedbat/coveragepy/issues/1319 .. _issue 1538: https://github.com/nedbat/coveragepy/issues/1538 .. _changes_7-0-5: ``` ### 7.0.5 ``` -------------------------- - Fix: On Python 3.7, a file with type annotations but no ``from __future__ import annotations`` would be missing statements in the coverage report. This is now fixed, closing `issue 1524`_. .. _issue 1524: https://github.com/nedbat/coveragepy/issues/1524 .. _changes_7-0-4: ``` ### 7.0.4 ``` -------------------------- - Performance: an internal cache of file names was accidentally disabled, resulting in sometimes drastic reductions in performance. This is now fixed, closing `issue 1527`_. Thanks to Ivan Ciuvalschii for the reproducible test case. .. _issue 1527: https://github.com/nedbat/coveragepy/issues/1527 .. _changes_7-0-3: ``` ### 7.0.3 ``` -------------------------- - Fix: when using pytest-cov or pytest-xdist, or perhaps both, the combining step could fail with ``assert row is not None`` using 7.0.2. This was due to a race condition that has always been possible and is still possible. In 7.0.1 and before, the error was silently swallowed by the combining code. Now it will produce a message "Couldn't combine data file" and ignore the data file as it used to do before 7.0.2. Closes `issue 1522`_. .. _issue 1522: https://github.com/nedbat/coveragepy/issues/1522 .. _changes_7-0-2: ``` ### 7.0.2 ``` -------------------------- - Fix: when using the ``[run] relative_files = True`` setting, a relative ``[paths]`` pattern was still being made absolute. This is now fixed, closing `issue 1519`_. - Fix: if Python doesn't provide tomllib, then TOML configuration files can only be read if coverage.py is installed with the ``[toml]`` extra. Coverage.py will raise an error if TOML support is not installed when it sees your settings are in a .toml file. But it didn't understand that ``[tools.coverage]`` was a valid section header, so the error wasn't reported if you used that header, and settings were silently ignored. This is now fixed, closing `issue 1516`_. - Fix: adjusted how decorators are traced on PyPy 7.3.10, fixing `issue 1515`_. - Fix: the ``coverage lcov`` report did not properly implement the ``--fail-under=MIN`` option. This has been fixed. - Refactor: added many type annotations, including a number of refactorings. This should not affect outward behavior, but they were a bit invasive in some places, so keep your eyes peeled for oddities. - Refactor: removed the vestigial and long untested support for Jython and IronPython. .. _issue 1515: https://github.com/nedbat/coveragepy/issues/1515 .. _issue 1516: https://github.com/nedbat/coveragepy/issues/1516 .. _issue 1519: https://github.com/nedbat/coveragepy/issues/1519 .. _changes_7-0-1: ``` ### 7.0.1 ``` -------------------------- - When checking if a file mapping resolved to a file that exists, we weren't considering files in .whl files. This is now fixed, closing `issue 1511`_. - File pattern rules were too strict, forbidding plus signs and curly braces in directory and file names. This is now fixed, closing `issue 1513`_. - Unusual Unicode or control characters in source files could prevent reporting. This is now fixed, closing `issue 1512`_. - The PyPy wheel now installs on PyPy 3.7, 3.8, and 3.9, closing `issue 1510`_. .. _issue 1510: https://github.com/nedbat/coveragepy/issues/1510 .. _issue 1511: https://github.com/nedbat/coveragepy/issues/1511 .. _issue 1512: https://github.com/nedbat/coveragepy/issues/1512 .. _issue 1513: https://github.com/nedbat/coveragepy/issues/1513 .. _changes_7-0-0: ``` ### 7.0.0 ``` -------------------------- Nothing new beyond 7.0.0b1. .. _changes_7-0-0b1: ``` ### 7.0.0b1 ``` ---------------------------- A number of changes have been made to file path handling, including pattern matching and path remapping with the ``[paths]`` setting (see :ref:`config_paths`). These changes might affect you, and require you to update your settings. (This release includes the changes from `6.6.0b1`__, since 6.6.0 was never released.) __ https://coverage.readthedocs.io/en/latest/changes.html#changes-6-6-0b1 - Changes to file pattern matching, which might require updating your configuration: - Previously, ``*`` would incorrectly match directory separators, making precise matching difficult. This is now fixed, closing `issue 1407`_. - Now ``**`` matches any number of nested directories, including none. - Improvements to combining data files when using the :ref:`config_run_relative_files` setting, which might require updating your configuration: - During ``coverage combine``, relative file paths are implicitly combined without needing a ``[paths]`` configuration setting. This also fixed `issue 991`_. - A ``[paths]`` setting like ``*/foo`` will now match ``foo/bar.py`` so that relative file paths can be combined more easily. - The :ref:`config_run_relative_files` setting is properly interpreted in more places, fixing `issue 1280`_. - When remapping file paths with ``[paths]``, a path will be remapped only if the resulting path exists. The documentation has long said the prefix had to exist, but it was never enforced. This fixes `issue 608`_, improves `issue 649`_, and closes `issue 757`_. - Reporting operations now implicitly use the ``[paths]`` setting to remap file paths within a single data file. Combining multiple files still requires the ``coverage combine`` step, but this simplifies some single-file situations. Closes `issue 1212`_ and `issue 713`_. - The ``coverage report`` command now has a ``--format=`` option. The original style is now ``--format=text``, and is the default. - Using ``--format=markdown`` will write the table in Markdown format, thanks to `Steve Oswald <pull 1479_>`_, closing `issue 1418`_. - Using ``--format=total`` will write a single total number to the output. This can be useful for making badges or writing status updates. - Combining data files with ``coverage combine`` now hashes the data files to skip files that add no new information. This can reduce the time needed. Many details affect the speed-up, but for coverage.py's own test suite, combining is about 40% faster. Closes `issue 1483`_. - When searching for completely un-executed files, coverage.py uses the presence of ``__init__.py`` files to determine which directories have source that could have been imported. However, `implicit namespace packages`_ don't require ``__init__.py``. A new setting ``[report] include_namespace_packages`` tells coverage.py to consider these directories during reporting. Thanks to `Felix Horvat <pull 1387_>`_ for the contribution. Closes `issue 1383`_ and `issue 1024`_. - Fixed environment variable expansion in pyproject.toml files. It was overly broad, causing errors outside of coverage.py settings, as described in `issue 1481`_ and `issue 1345`_. This is now fixed, but in rare cases will require changing your pyproject.toml to quote non-string values that use environment substitution. - An empty file has a coverage total of 100%, but used to fail with ``--fail-under``. This has been fixed, closing `issue 1470`_. - The text report table no longer writes out two separator lines if there are no files listed in the table. One is plenty. - Fixed a mis-measurement of a strange use of wildcard alternatives in match/case statements, closing `issue 1421`_. - Fixed internal logic that prevented coverage.py from running on implementations other than CPython or PyPy (`issue 1474`_). - The deprecated ``[run] note`` setting has been completely removed. .. _implicit namespace packages: https://peps.python.org/pep-0420/ .. _issue 608: https://github.com/nedbat/coveragepy/issues/608 .. _issue 649: https://github.com/nedbat/coveragepy/issues/649 .. _issue 713: https://github.com/nedbat/coveragepy/issues/713 .. _issue 757: https://github.com/nedbat/coveragepy/issues/757 .. _issue 991: https://github.com/nedbat/coveragepy/issues/991 .. _issue 1024: https://github.com/nedbat/coveragepy/issues/1024 .. _issue 1212: https://github.com/nedbat/coveragepy/issues/1212 .. _issue 1280: https://github.com/nedbat/coveragepy/issues/1280 .. _issue 1345: https://github.com/nedbat/coveragepy/issues/1345 .. _issue 1383: https://github.com/nedbat/coveragepy/issues/1383 .. _issue 1407: https://github.com/nedbat/coveragepy/issues/1407 .. _issue 1418: https://github.com/nedbat/coveragepy/issues/1418 .. _issue 1421: https://github.com/nedbat/coveragepy/issues/1421 .. _issue 1470: https://github.com/nedbat/coveragepy/issues/1470 .. _issue 1474: https://github.com/nedbat/coveragepy/issues/1474 .. _issue 1481: https://github.com/nedbat/coveragepy/issues/1481 .. _issue 1483: https://github.com/nedbat/coveragepy/issues/1483 .. _pull 1387: https://github.com/nedbat/coveragepy/pull/1387 .. _pull 1479: https://github.com/nedbat/coveragepy/pull/1479 .. _changes_6-6-0b1: ``` ### 6.6.0b1 ``` ---------------------------- (Note: 6.6.0 final was never released.
